How do angels help to achieve a magnificent spiritual death?

"This rare point should be well remembered that Jibra'ili cure is done with knowledge, Mika'ili cure by wisdom, Israfili cure by giryah-u zari (supplication) and Divine love, and Izra'ili cure by effacement (removal of sins) and annihilation (in the sense of merging the soul into the Light and then reviving it with a greater strength). The last one is the effective cure. For the perfect taqwa (piety) and complete purification lies only in a magnificent (spiritual) death happens to soul in this life. And this is a very great miracle, for in it is observed, not only the scene of death, but also a glimpse of the next life."
